are piston-heads 9 and 10, connected'by piston-rods ll and 12 with the piston-heads 13 and 14 of the steam-cylinders, the rods working in appropriate stutiing-boxes 15 and 16 carried by the opp cylinders. Arranged within each of the cyl-' inders 3 and 4 are two rods 17 and 18, 19 and carries two and 20 carries a collar 23 and rods work in suitable bearings cylinder-heads 3 and 4, and work loosely 1n orifices provided in the piston-heads 13 and 14-. The outer end of each' of the rods.17 and :20, carries a valve 5-and 26 respectively, and a coiled spring 27 is carried by the inosed ends of the formed in the xier end of each of the rods-and bears upon the outside of the inner heads ofthe cylinder 3 and 4, said springs serving normally to ho the valves in close juxtaposition to the outer heads of the cylinders 3'and 4.: Thesevalves work in casings 27 and28 that project from the outer heads' of t e cylinders 3 an Connecting with the ylinders Land 2 is a water-supply pipe 29 Fig. 4) that leads to a suitable source of supply, and includes a branch pipe'30 controlled by a valve 31 to pum 'water' from the hold of the vessel. Tapped into each of the cylinders 1 and 1s a;pipe-32, Fig; 3 which communi ates with a valve-casing 33, the latter being in communication with an air-dome 34,and coupled with the pipe 32 is a, branch 1pc 35 controlled by a valve 36, the object of the branch pipe being to supply water to anypart of a vessel in case '0 re. With the casing 33 are connected six pipes 37, 38, 39, 40, 41, and 42, Of these the pipes 39 and 40 discharge in the line of the keel,w hile the remaining pipes discharge thereto, and are utilized for steering purposes, whereas the former pipes are utilized for propulsion.

As stated, the various objects designed are secured by employing alternating 'puL sations or jets of water, and one of the novel features resides in the employment of pneumatic pressure for controlling eration of the valves thatppen or'close t pipes 3742,a detail of this arrangement being shown in-Fig. 3,, in-which but two. of the valves 43 and 44, and one v'alvej45 for controlling passage of water through the pipe 40 are s 43 and 44 has connected with it a stem 46 and 47 which projects, through one end of hown.. Each of the valves at right angles the opon the stems within the casing serving nor- (if-the valves outlet 57 and the the valve-casing, coiled springs 48 arranged mally to hold the valves seated. The valve 45 is provided with a similar stem 49 and spring 50 for holding it seated. It is to be understood, of course, that the six valves cooperating with the pipes 37-42 operate independently. Connected with each of the valve-casings of the pipes is one 'end ofa pipe 51, 52, 53, .54, 55, and 56 respectively, the other end of each of which connects with a pipe 57 and 58 respectively which connect with the valves. 61, 62, 63,64, and 66 carried by the pipes 51,52,533, 54, 55 and 56 respectively the-four pipes 58, 59, 57 and 60 being tapped into the valve-casings 27 and-28. Arranged adjacent to the valve-casings 27 and 28 is 'apipe 67 that leads to a suit able reservoir containing air under pressure, and leading from thepipc 67 are two brancl pipes 68 and 69 that are tapped into the casings, 27 and 28 respectively. Each and 26 is provided with a. port- 70 and 71 respectively which are of a. size to establish'connnunication between the pipes 58'and 68, and the outlet 58"-and the pipes 57 and 69. I Each of the cylinders? and 4 is rovided with two ports 72, 73 and 74, 75, respectively, that coiiperate' with two slide valves 76 and 77 workingin suitable chests 78 combined with the cylinders, clearlyshown in Fig, 2. Combined with the exterior of the outer heads of the cylinders 3 and 4 and with the chests are shafts 79 and 80 respectively, one being disposed above and the other below the horizontal axes of the cylinder. Journaled upon the rods. 79 and 80 are arms 81", '82, 83- and .84, and with these are connected the rods 18 and19 and the valve-rods 85 and 86.

Connecting with the air-supply pipe 67 aretwo branch pipes 87 and 94, the former of which is tapped into the larger end of the air dom'e 34. Mounted upon the pipe 67 1s a valve-casing 89, shown in detail in 7, and in which is mounted a Valve 90 having a. transverse port 91 arranged, under certain-conditions, to register with the pipe 67, a coiled spring 92 encircling the stem 93 of the valve serving to hold the same normally seated.

e pipe 67- has connected, with branch pipe 94, and the pipe 87 has connected with it a braneh-"95, and these two branches support'a pressure-gage'96. having two hands, one'of which indicates the pres ita ' sure in the-pipe 67, and. the other the pressure in the pipe 87.

When it is desired to operate the mechanism of propulsion, steam is allowed to pass through the pipe to the valves 76 and 77 which control the admission of steam to the cylinders fallowmg steam to pass into cylinder 3 vtached to th 3 and 4. In'the position in which dotted lines in Fig.

the cylinders are shown in Fig. 2, steam will 0 in the act of passing valve. 77 to the piston-head 14 which being forced forward, in consequence, will produce a two-fold action; namely, striking the collar '22 ou the. rod 19 which is attached to a revolving shaft 80, the latter connecting with the valve7 6 of the opposite cylinder 3, it willcause the valve 76 to assume such place as will 'set its openings. in juxtaposition with the opening of .thesteam-pipe 97, thus in cylinder 3 'to force the llar 24,011 the rod 20 which the valve 26, willbring the valve 26 into such position between the against the co is attached-to openings of said as to establish communication by means of the to the piston-head former backward; I and secondly, the piston-head 14, striking compressed-air pipe 69 and the-pipe 57 which connects with the cooks that regulate the passage of the air to the. Jet-valves 42, 41, 0,39, 37 and'38. From this brlef'descri )tion of the action produced bythe adf mission of steam to .cylinder '4, it Wlll be evident that the time during which the valve 26 will remain in position to'allow the passage of compressed-air from the pipe 67 to the cocks, as, well as the interval betweeneach successive opening and closing of said valve 26, will be determined by the greater or less velocity inthe motion of the pistonhead, the velocity of the latter in turn upon the greater or less amount of steam admitted to the cylinders.

Movements similar to those in cylinder 4 will be produced by the admission of steam and the piston-head 13 being" forced backward, will release pressure from the collar 23 on the rod 17; which latter be-' mg brought to its normal position by the spring 2' 4 will cause the same the posit'on as indicated air-valve 26, t s shutting ofi' tion between the and establishing} communication between the pipe 58 andthe atmosphere at 57. Furthermore, the piston-head 13 is forced back. and strikes the collar 21 attached to the this latter being connected by a shaft the steam-valve 77, will cause the valve 7 7 to move in the same direction asthat of the piston-head 13, thus allowing the steam to pass in regard toconnnunicathrough to the cylinder 4. The action of the cylinders will be. alternated, this being due as well to the alternate opening and closing of the valves 76 and 77,'as-to in structure of the valves themselves. When the steam pumps are in motion in depending air-valve 25 to as-- air-pipe 58 and the pipe 68 no rod- 18,

79 with the difference the manner. described the piston-rod 12 ata i e piston-head '10 in the watercylmder 2, will cause the piston-head 10 to move forward thus by the force offisuction drawing the water into' the cylinder -2 through the water-valve 97. indicated by 2. As the piston-head 35 pharge practically '45 the water on the air {returns in the opposite direction, 'it forces the water .thus drawn in, through the valve 7 and through this to the pipes 98, (indicated by dotted lines in Fig. 3), and 29 5 whence it passes to the jet-valves 42, 41 etc.

While this action is taking place, water is likewise being drawn in on the other side of the piston-head through the valve 99, Fig. 3, the water on the return stroke of the piston-head being forced through the valve 8 thence through the pipes 98v and 29 to the jet-valves. A similar operation takes place in cylinder 1, the water being admitted through the valve 100 and passing outward through the valves 5 and 6, and the pipes 98 and 29.

The water that is forced to the several jet-valvesby the action ofthe pumps will remain under pressure until the jet-valves are opened by the force of the compressed air from the air-pipes 54, 55, 5.6, 53, 52 and 51. On inspection of the drawings, it will be noted .that, while the jet-valves are arranged in pairs as shown in Figs. 2 and 3, the pipes that convey the compressed air to 'the jet-valves are so disposed as to correspond alternately now to one and then to the other cylinder of the pump. Since, been stated, the action of the pumps is alternated, such arrangement of the air-pipes will result in an alternated discharge of water from the several pairs of jet-valves, with such brief interval, however, between each alternate discharge asto make said discontinuous, and thus do away with the dead-zone that would result were there but a single continuous discharge of water. The passage'of the compressed air to the pipes 56,55, 54,53, 52 and'51, and

'ZO'thence, to the jetvalves is regulated by the 3 cocks 66, 65,-64,61, 62 and 63,.and the valve 89, shown in detail in Fig. '7. The purpose of the valve 89 is to prevent the passage of air from the reservoir until the ressure of in the airome 34 is sufiicientlygreat to cause the opening 91 of 7 said valve 89 to be set in juxtaposition with the air-pipe 67. It will be understood therefore that under such conditions the jet-valves can only be opened to allow the discharge 'of water when this latter is under a given pressure, determined both by the greater or less velocity in the action of the pteampumps and by the greater or less resistance I .55 of the spring 92 in the valve 89, said spring being of such construction as toallow of its being setto any given tension. It will also be understood that when the mechanism is in operat1on, .other things being equal, the intervals betweenthe successive opening and closing of valve89 will be so brief as practically to keep said valve continually open. 7 As the compressed air asses. through the valve 89 to thepipe to thepipe 57 w1ll be determined by the juxtaposed jet nally adjacent in the line of the keel to d1scharge at the end of the vessel and pairs of v as has.

Lastly the opening and closin of the cocks 66, 65, (34, 61, 62 and 63, will be regulated by any suitable electric device operated from a key-board or levers in the engine-room or elsewhere, the electrical mechanism forming no part of the present invention."
